This has been tried multiple times. Micropayments just don’t work well. People don’t want to create an account, break out their CC, and enter their info just for a 5c transaction. You also can’t even profitably charge a CC 5c, so you need to charge something like $5. Unlike music, most people can envision consuming $5 worth of news media unless they already have a strong preference for a publication like the NYT or WSJ.
